What is plotVR about? 5 5

Data Scientists love to visualise... E Not the "real" thing, so N x o p w e n a n s d i v t e h e , n m g e o a 3 D n w h i l e . . . 6

But there are some issues to solve here... How do we bring the data from the workstation to the mobile device? ■ Can we do both VR and AR? ■ Can we do it in HTML or do we need an app for that? ■ How do we navigate when we are in VR? ■ Does it need to cost something? ■ Can I create all that in my own free time? ■ 7

Features Matrix VR AR 3D Technology Availabilit y HTML three.js GitHub ✓ ✕ ✓ (ugly on iOS) (no nice lib?) iOS SceneKit, GitHub ✓ ✓ ✓ ARKit, GVR Android ✓ planned planned OpenGL, GitHub ARCore, GVR 8

Can I haz plotVR? Python: ■ pip install "git+https://github.com/thomann/plotVR#egg=plotvr&subdirectory=plotVR-py" ■ R: ■ devtools::install_github('thomann/plotVR', subdir='plotVR-R') ■ iOS-App ■ https://github.com/thomann/PlotAR-ios (needs XCode and a free personal team) ■ To have you as an early tester: philipp.thomann@d-one.ai ■ Soon via AppStore TestFlight with a shared public link? ■ Android-App: ■ https://github.com/thomann/plotVR-android ■ https://github.com/thomann/plotVR-android/releases ■ 13

Outlook / Vision Add text, lines, surfaces to 3D plots ■ Make scenery nicer ■ PyPI, CRAN, AppStore, GooglePlay ■ Solidify protocol ■ Ideas: HTTPS / Authentifcation / Authorisation ■ User Jupyter-Tornado as server? ■ Interface to plotly, ggplot? ■ Namespaces on server → central plotVR server, e.g. on cloud/premise ■ 14

Thanks All the giants' shoulders this project stands on: ■ Cardboard, GVR, ARKit, Jupyter, Tornado, requests, pyqrcode, three.js, … D ONE for being a really cool employer to send me here ■ EuroPython for giving me the opportunity to work more on this! ■ And all the future contributors to these projects ;-) ■ 15
